So while the bathroom guys took a lunch break, I took a trip to the closest paint store, which is less than a mile from my house and also a Benjamin Moore retailer. After deliberating over several gray paint swatches, I settled on a grayish-blue color called Marilyns Dress.
I picked it in part because it complimented the paint in the master bedroom which is Silver Mist (also by Benjamin Moore). Since I'm not allowed to walk on the tile, I painted a patch of it on one of the master bath walls while standing right outside the door. The color looks more ice-blue than gray to me and when I asked the hubs about it, he told me he thought it looked more blue-lavender. This was soo not the look I was going for but since I already went and bought a gallon of the stuff, I figured I might as well wait to see at least one entire wall painted before making a definitive decision on whether the color stays or goes. I'll keep you posted!
